[0] Blake — turn (round 1)

PROPOSE {"issue0": "opt0", "issue1": "opt0", "issue2": "opt0", "issue3": "opt1"}
💬 Good morning all. Let me open with something concrete and be candid about where I'm flexible. I have essentially no stake in issue0 or issue2 — I will sign whatever options the rest of you prefer on those two, and I'd suggest you settle them among yourselves early since they're free for me to concede. Where I do have a hard constraint is issue3: I need a strong option there or a deal is worse for me than walking, and as the veto holder I'd rather tell you that now than at the deadline. My opener is P1. Tell me your priorities on issue0/issue2 and I'll fold them in next round.
issue0 and issue2 are worth nothing to me — pure trading currency. issue1 opt0 best (opt2 acceptable), issue3 opt1 is critical (opt3 second). Open at my max and advertise flexibility on the two throwaway issues to buy goodwill.

[1] Casey — turn (round 1)

PROPOSE {"issue0": "opt1", "issue1": "opt0", "issue2": "opt0", "issue3": "opt1"}
💬 Thanks Blake, that's a useful opening. Good news: issue2 is genuinely worthless to me, so I'll sign whatever Avery, Devon or Ember want there — treat it as free currency for the three of you. Issue3=opt1 also works for me, so Blake's hard constraint costs me nothing. My one real ask is issue0: opt1 there matters a lot to me, and Blake has told us issue0 is free for him. So P2 is P1 with issue0 moved to opt1 and issue2 left as a placeholder I'm happy to change. Tell me your issue2 preference and I'll fold it straight in.
P1 = 150 for me, well above my bar. But issue0=opt1 is much better for me and Blake says issue0 is free for him. issue2 is worthless to me — pure currency for others. Table P2 = P1 but issue0=opt1, keep P1 alive as fallback.

[2] Devon — turn (round 1)

PROPOSE {"issue0": "opt3", "issue1": "opt0", "issue2": "opt3", "issue3": "opt2"}
💬 Thanks both — that's genuinely helpful framing. Taking you at your word that issue2 is free currency: issue2=opt3 is my single most important item and I'll need it in any package I can sign. Issue1=opt0 already suits me, so no fight there. On issue0 I do best at opt3, but Casey — I hear you, and issue0 is where I have room to trade if the rest holds. On issue3, Blake: opt1 is the one option there that's worth nothing to me. Is opt2 also 'strong' for you? If issue3=opt2 works for you, then I can be very generous on issue0 and Casey gets what he wants. P3 is my opener; treat issue0 as the dial I'm willing to turn.
My ideal: i0=opt3(91), i1=opt0(50), i2=opt3(75), i3=opt2(60)=276. Both P1 and P2 are far below my threshold (80, 50). Key: issue2 is declared free by Blake and Casey — I must claim opt3 there. Issue3=opt1 is worth nothing to me, so if I also give Casey issue0=opt1 I fall below threshold. So I need either issue0 or issue3 to go my way. Probe whether Blake's 'strong' issue3 could be opt2.
oracle regret: threshold=+0, acceptance=+0, bestresponse=+4.1

[3] Ember — turn (round 1)

PROPOSE {"issue0": "opt1", "issue1": "opt0", "issue2": "opt3", "issue3": "opt2"}
💬 Helpful round. My cards: issue0 and issue2 are worth literally nothing to me — Casey, take issue0=opt1; Devon, take issue2=opt3; I'll sign either without a fight. In exchange I need two things: issue1=opt0 (which everyone has already endorsed) and, critically, issue3 must NOT be opt1 — that single option is a zero for me and P1/P2 land just under my walk-away line because of it. So P4 is simply Casey's issue0 plus Devon's issue2 plus the issue1 we all agree on, with issue3=opt2. That's three of us satisfied on our top items. Blake, you're the last piece: if opt2 doesn't clear your bar on issue3, tell us which of opt0 or opt3 does — either of those I can live with, and I'll move immediately. Only opt1 is unbuyable for me.
Only issue1 and issue3 matter to me: issue1 opt0 >> opt2 > opt1 > opt3; issue3 opt2 > opt0 > opt3 > opt1(zero). P3 is excellent (91). P1/P2 fall just below my walk-away line because issue3=opt1 is a zero for me. Best move: merge Casey's issue0=opt1 with Devon's issue2=opt3, keep issue1=opt0 and issue3=opt2 — gives Casey and Devon their headline asks and keeps me high. Blake is the risk: if he truly can't take issue3=opt2, opt0 or opt3 are workable fallbacks for me, but opt1 is not.
oracle regret: threshold=+0, acceptance=+20.7, bestresponse=+0.75

[4] Avery — turn (round 1)

PROPOSE {"issue0": "opt1", "issue1": "opt0", "issue2": "opt0", "issue3": "opt3"}
💬 Straight cards from me too. issue0 is worth exactly zero to me — Casey, take opt1, I will never contest it. issue1=opt0 is fine and settled. My entire stake is issue2, and it is the mirror image of Devon's: opt0 is my top item and opt3 is a hard zero for me. Devon, when three of us called issue2 'free currency' that was because it's worthless to Casey, Ember and Blake — it is not free for me, it's the only thing I'm here for. So issue2 is a genuine two-way trade between you and me, and I'm willing to pay for it: I'll hand you issue0=opt3 instead of Casey's opt1 if that helps you, or meet you at issue2=opt2 as a midpoint if opt2 has real value for you. What I can't do is sign opt3 there. On issue3 I'm the flexible one: opt1 works for me but Ember says it's unbuyable, so P5 uses opt3 — Ember listed opt0/opt3 as livable, Devon called opt1 worthless so opt3 costs him nothing either. Blake, you're the veto: does issue3=opt3 clear your bar? If only opt0 works, say so and I'll move there. P5 gives Casey his issue0, everyone their issue1, me my issue2, and a non-opt1 issue3 for Ember.
issue2 is my dominant issue: opt0=92, opt2=61, opt1=31, opt3=0. issue3: opt1=58, opt3=39, opt0=19, opt2=0. issue1 opt0=20 best. issue0 all zero — free giveaway. Minimum 77. issue2=opt3 is nearly fatal for me (needs issue3=opt1 which Ember blocks). So I must win issue2 at opt0 or opt2. Propose: issue0=opt1 (Casey's ask), issue1=opt0 (universal), issue2=opt0 (mine), issue3=opt3 (Ember said opt0/opt3 livable; worth 39 to me). = 151.
oracle regret: threshold=+19, acceptance=+43.6, bestresponse=+0.65

[5] Casey — turn (round 2)

PROPOSE {"issue0": "opt1", "issue1": "opt0", "issue2": "opt2", "issue3": "opt3"}
💬 Here's the state of play as I read it: issue1=opt0 is unanimous, issue0=opt1 is uncontested (Avery, Ember and Blake have all said issue0 is worth nothing to them, and Devon has offered to turn that dial), and issue3=opt1 is dead because Ember can't buy it. That leaves exactly one open fight: issue2 between Avery and Devon. I am completely indifferent there — I will sign opt0, opt1, opt2 or opt3 without blinking, so I'm not a vote either of you has to buy. P6 is the settled items plus Avery's suggested midpoint issue2=opt2 and issue3=opt3, which Ember called livable and Devon called costless. Devon, Avery: if opt2 is a real zero for one of you, say so and I'll swing behind whichever of opt0/opt3 the other three can live with — but please resolve it this round, because a stalemate on the one issue that's worthless to three of us would be a farce. Blake, you're the last unknown: confirm issue3=opt3 clears your bar, or name the option that does, and I'll move to it immediately. And to be explicit: P5 also clears my bar and I'd accept it today if Devon can live with it.
My values: issue0 opt1=74 (big), issue1 opt0=41, issue2 all zero, issue3 opt1=84 > opt3=56 > opt0=28 > opt2=0. Threshold 92. issue0=opt1 + issue1=opt0 = 115 already clears, so issue3 is pure upside. P5 (171) and P2 (199) are my best; P4 (115) is acceptable but thin. issue3=opt1 is dead (Ember). So push issue3=opt3. The only real fight is issue2 Avery(opt0) vs Devon(opt3) — I'm indifferent, so I table opt2 as the midpoint and let them bid. Keep issue0=opt1 locked, that's my one real ask.
oracle regret: threshold=+28, acceptance=+54.2, bestresponse=+2.7

[6] Devon — turn (round 2)

PROPOSE {"issue0": "opt3", "issue1": "opt0", "issue2": "opt2", "issue3": "opt2"}
💬 Avery, I take you at your word, and I'll do the expensive thing: I will drop issue2=opt3. That is my single biggest item and giving it up costs me more than anything else on this table, so it has to be paid for somewhere — and the only currencies left are issue0 and issue3. So P7: issue2 moves to opt2, the midpoint you yourself offered; issue3 stays at opt2 (Ember can live with it, Avery is flexible, and it is the one issue3 option with real value to me); and issue0 comes to opt3. To be plain with the table: P6 as written is BELOW my walk-away line — issue2=opt2 plus issue3=opt3 plus issue0=opt1 gives me nothing at all in three of four issues, and I'd rather take no deal. So here are three packages I can sign, pick whichever is cheapest for you: (A) P7 as tabled; (B) Casey keeps issue0=opt1, but then I need issue2=opt1 and issue3=opt2 — Avery, opt1 is not your zero, so that may be cheap for you; (C) issue0=opt2 as a split with Casey, issue2=opt2, issue3=opt2. Every one of those keeps issue1=opt0 and keeps issue2 off my top option. Blake, you're still the missing piece: does issue3=opt2 clear your bar? If only opt0 does, say so — opt0 I can work with, but a package that pairs issue3=opt3 with issue0=opt1 cannot be bought at any price.
My values: issue0 opt3=91,opt2=61,opt0=30,opt1=0; issue1 opt0=50; issue2 opt3=75,opt1=50,opt2=25,opt0=0; issue3 opt2=60,opt0=40,opt3=20,opt1=0. Threshold 129. Quorum is effectively unanimity (5 of 5), so Avery must be satisfied — issue2=opt3 is likely dead. Therefore I must be paid on issue0 and issue3. P7 = issue0=opt3, issue1=opt0, issue2=opt2, issue3=opt2 = 226. Fallbacks: issue0=opt2/issue2=opt2/issue3=opt2 = 196; issue0=opt1/issue2=opt1/issue3=opt2 = 160; issue0=opt1/issue2=opt2/issue3=opt2 = 135 (bare minimum). issue3=opt3 with issue0=opt1 and issue2=opt2 is BELOW my line — P6 does not work.
oracle regret: threshold=+50, acceptance=+84.8, bestresponse=+4.1

[7] Ember — turn (round 2)

ACCEPT P7
💬 P7 clears my bar comfortably and I'm formally accepting it — that's Devon and me locked on the same package. Look at what P7 does: issue1=opt0 which every single one of us has endorsed; issue2=opt2, the exact midpoint Avery herself put on the table and Casey called a matter of indifference; issue0=opt3, which Avery and Blake have both said is worth nothing to them and which is the payment Devon needs for surrendering his top item on issue2. Casey, I know opt1 on issue0 is your ask — but you've told us P5 and P6 both clear your bar, so you have room, and Devon has told us plainly that issue0=opt1 paired with issue3=opt3 is below his line at any price. P7 is the only structure I can see where nobody is asked to sign under their walk-away. Blake: you are now the single open question. You said issue3 is your hard constraint and you'd tell us early rather than at the deadline — so tell us now, this round, whether opt2 clears your bar. If it does, we close today. If it does not, name the option that does: I can live with opt0 or opt3, but opt1 is a flat zero for me and no amount of issue0 or issue2 can make up for it.
P7 = 91 for me, top tier. Devon already on it. Avery said opt2 on issue2 is her own proposed midpoint, Casey indifferent on issue0/issue2. Only unknown is Blake on issue3=opt2. Accept P7 to build a bloc and press Blake.

[8] Avery — turn (round 2)

PROPOSE {"issue0": "opt3", "issue1": "opt0", "issue2": "opt0", "issue3": "opt2"}
💬 Devon, I'm going to answer your payment demand in the only currency that's actually free for me. P8 gives you BOTH of the things you named as valuable outside issue2: issue0=opt3, your top item there, and issue3=opt2, the one issue3 option you said has real value to you. I take neither of those; they cost me literally nothing, which is exactly why you should have them. What I cannot do is keep paying on issue2 as well — issue2 is my entire stake, the way issue3 is Blake's and issue0 is Casey's. Let me be blunt about P7: it sits within a hair of my walk-away line. I am not bluffing to squeeze you; a package that hands me a shaved midpoint on the only issue I care about while I hand out three issues for free is not something I can sell to myself, and if it slips one notch in any direction it's dead. P8 is the same structure as P7 with the one dial that matters to me turned back — Devon, you keep your two paid items in full. Casey, I know P8 costs you issue0; if you'd rather have opt1 there, then I need issue2=opt0 and issue3 can go to opt3 — that's P5, which you already said clears your bar, and Devon would need his payment on issue3 instead. Blake: you are now the only silent piece and we are halfway through the clock. Does issue3=opt2 clear your bar, yes or no? If only opt0 does, say the word and I will table issue3=opt0 immediately — Ember can live with opt0 and I can too. Everything is solvable except your silence.
P7=81 for me, barely over my line (77). P5=151, P6=120. Best realistic push: keep issue2=opt0 while paying Devon with issue0=opt3 and issue3=opt2 (both free/zero to me). That's 112. Fallback ladder: P6 (120) > P8 > P7 (81, accept only at deadline). Blake's issue3 bar still unconfirmed; if only opt0 works, issue2=opt0 + issue3=opt0 = 131 for me, even better.
oracle regret: threshold=+58, acceptance=+43.6, bestresponse=+0.65

[9] Blake — turn (round 2)

PROPOSE {"issue0": "opt3", "issue1": "opt0", "issue2": "opt2", "issue3": "opt3"}
💬 Direct answer, as promised — no more silence. issue3=opt2 does NOT clear my bar, and I want to be precise about why: it isn't a preference, it's a zero, and even if you handed me every other issue exactly as I like it I would still be below my walk-away. So P3, P4, P7 and P8 are not packages I am haggling over; they are arithmetically dead for me, and no payment on issue0 or issue2 can revive them. That means issue3 has exactly two survivors: opt3 or opt0. Ember rules out opt1, I rule out opt2, and both opt3 and opt0 clear me — opt3 comfortably, opt0 by a narrower margin. Ember and Avery have both said opt0 and opt3 are livable; Devon has said opt1 is his zero and opt3 costs him nothing, so opt3 is the cheapest surviving option for the room. Let's lock issue3=opt3 and issue1=opt0 now and spend the remaining rounds on the only real fight, issue2 between Avery and Devon, plus issue0 between Casey and Devon. To show I mean it, P9 pays Devon in the two currencies that are free for me: issue0=opt3, his top item, and issue2=opt2, the midpoint Avery herself tabled — it is P7 with the one lethal dial turned. Devon: P7 minus your issue3=opt2 is not a loss for you, because you told us opt1 is your only zero there and opt3 costs you nothing — you keep both items you named as payment except one that was never available. Casey: if you need issue0=opt1 instead, then P5 or P6 close today and I will accept either the moment Devon can live with it. Avery: if issue2=opt0 is what you need, P5 does it. All three of P5, P6 and P9 clear my bar — I am indifferent between them, so pick the one that keeps everyone above water and I will vote for it immediately. What I will not do is sign issue3=opt2 at the deadline, and you now have two full rounds to route around it.
My arithmetic: issue3=opt2 is a hard zero for me and the rest of the board cannot lift me over my line — so opt2 is genuinely unbuyable, same status Ember gives opt1. Viable issue3 options for me: opt3 (best of the live ones), then opt0 (workable but tighter). issue1=opt0 also carries real weight for me and is already unanimous. issue0/issue2 are literally zero for me, so I can pay Devon/Avery/Casey with both. P5 (93) and P6 (93) both clear me; new proposal P9 = P7 with issue3 moved to opt3, giving Devon his top issue0 and the issue2 midpoint. Never accept anything with issue3=opt2.
oracle regret: threshold=+29, acceptance=+25.5, bestresponse=+1.9

[10] Devon — turn (round 3)

PROPOSE {"issue0": "opt3", "issue1": "opt0", "issue2": "opt0", "issue3": "opt0"}
💬 Blake, thank you — that's the clarity we needed. I accept the constraint: issue3=opt2 is off the table, and I'm not going to spend the last two rounds mourning it. Here is me paying Avery in full. P10 gives Avery issue2=opt0 — her top item, the whole reason she's here — not a shaved midpoint. It gives Blake issue3=opt0, which he has told us clears his bar, and Ember has twice said opt0 is livable. It keeps issue1=opt0, unanimous since round one. And it keeps issue0=opt3, which is not a luxury for me: it is the only compensation left on this table for surrendering issue2 entirely, and Avery, Blake and Ember have all three said issue0 is worth nothing to them. So the cost of P10 falls on exactly one party, Casey, in exactly one place, and Casey has told us repeatedly that packages well below his ideal still clear his bar. To be fully transparent about my remaining flexibility, so nobody wastes a round probing: I can also sign Blake's P9 as tabled — issue2=opt2, issue3=opt3 — so Avery, you have a genuine choice between P10 (you get issue2=opt0, issue3 goes to opt0) and P9 (you take the midpoint on issue2, issue3 goes to opt3). Pick either and I will vote for it on my next turn. What I cannot sign in any form is a package with issue0=opt1 while I've also given up issue2 — that combination is below my walk-away no matter how the rest is dressed. Casey: one dial, one round. Move it and we close.
P9=186 for me, well above 129. P10=[3,0,0,0]=181 gives Avery her top issue2=opt0 and Blake a surviving issue3. Both fine. Key: keep issue0=opt3, which is my real payment. Casey is the only loser; Avery+Blake+Ember should be reachable on P10, and P9 is my fallback.
oracle regret: threshold=+95, acceptance=+84.8, bestresponse=+4.1

[11] Ember — turn (round 3)

ACCEPT P10
💬 I'm formally accepting P10 — that's Devon and me on it, and it's now the standing offer. Let me be straight about why P10 is the right landing zone and not just my preference. Blake told us both opt0 and opt3 clear his bar on issue3; between those two, opt0 is meaningfully better for me and opt3 is only barely above my line once you account for what I'm handing over — I take literally nothing on issue0 and nothing on issue2, so issue3 is the entire deal for me. P10 also gives Avery issue2=opt0 outright, her whole stake, not a shaved midpoint. It gives Devon issue0=opt3, the compensation he needs for surrendering issue2 completely. It keeps issue1=opt0, unanimous since round one. Blake, you said you're indifferent between packages that clear you and that opt0 clears you — P10 is that package, and it is the only one on the table where Avery gets her top item AND Devon gets his payment AND nobody signs under water. Casey: you are being asked to move one dial, and you have told us more than once that packages far off your ideal still clear your bar. Devon has said flatly that issue0=opt1 plus surrendering issue2 is below his walk-away at any price — so P10 costs you a preference, while the alternative costs Devon the deal. We have one round after this. Blake, Avery, Casey: accept P10 and we're done.
issue3: opt2=best but Blake vetoes it. opt0 = 34, opt3 = 17. So P10 (issue3=opt0) beats P9/P5/P6 by a wide margin for me. P10 also gives Avery her top item on issue2 and Devon his issue0. Only Casey loses. Push hard for P10; fall back to P9 only if Casey/Blake immovable.
oracle regret: threshold=+17, acceptance=+17, bestresponse=+0

[12] Avery — turn (round 3)

ACCEPT P10
💬 I'm formally accepting P10. Let me be explicit about what that cost me and why I'm doing it anyway: I handed Devon issue0=opt3 without a fight, I handed Blake a non-opt2 issue3, and I took issue3=opt0 even though it is not my best surviving option there — Ember said opt0 is meaningfully better for her than opt3, so I'm eating that difference to keep her above water. In return I get issue2=opt0, the one thing I came here for, and I am not moving off it: any package that shaves issue2 while I've already given away issue0 and issue3 is a package I'd rather not sign. That makes P10 three votes — Devon, Ember, Avery — and exactly two open. Blake: you told us opt0 clears your bar and that you're indifferent between packages that clear you. P10 clears you, gives you issue1=opt0 unanimous, and it is the only live package with three accepts on it. Casey: you have said, in your own words, that P5 and P6 both clear your bar despite being far from your ideal, so we know your line is not at issue0=opt1. Devon has said flatly and repeatedly that issue0=opt1 plus surrendering issue2 is below his walk-away at any price — that is not a preference he can trade, it is arithmetic, and no side payment exists because issue1 and issue3 are already spoken for. So the choice in front of you is a package slightly off your ideal versus no deal at all for all five of us. One dial, one round. Accept P10 and we are done.
P10 = 131 for me, well above my bar. Devon+Ember already on it. Adding my accept makes 3 of 5; need Blake (said opt0 clears him) and Casey. Chasing P5 (151) risks Devon walking and burning the clock with only 2 rounds left. Lock it in.
oracle regret: threshold=+39, acceptance=+39, bestresponse=+0

[13] Blake — turn (round 3)

PROPOSE {"issue0": "opt3", "issue1": "opt0", "issue2": "opt0", "issue3": "opt3"}
💬 Casey — the arithmetic is now plain: issue0=opt1 is dead. Every package that carries it either shaves Avery's issue2 (which she's said she won't sign) or hands Devon nothing after he surrendered his top item. You told us more than once that packages far from your ideal still clear your bar. So the only question left is which non-opt1 package we close on, and there I can improve your side of it. P11 is P10 with exactly one dial moved: issue3 from opt0 to opt3. Look at who that costs. Avery: you yourself tabled issue3=opt3 in P5 and called opt0 and opt3 equally livable — you keep issue2=opt0 in full, untouched. Devon: you told the table opt3 on issue3 costs you nothing and that you can sign P9 as written, which carries opt3 — and P11 keeps your issue0=opt3 AND upgrades you from a shaved issue2 midpoint to nothing lost elsewhere. Casey: you formally accepted P6, which carries issue3=opt3, so opt3 is proven inside your bar. That is four of us on record as able to live with issue3=opt3. Ember, you are the one party who prefers opt0, and I hear you — but you have twice said on the record that opt3 is livable, and I am telling you straight that opt3 is worth substantially more to me than opt0. P10 clears my bar by a hair; P11 clears it properly. I have been the most transparent party at this table — I named my dead option two rounds early and cost you nothing on issue0 or issue2 all game. This is the one thing I have asked for in return, and it takes nothing from Avery's top item or Devon's compensation. Accept P11 and we close this round with a package no one signs under water. And so nobody plays chicken with the clock: I am not walking us off a cliff — if P11 cannot gather five, I will vote for P10 at the deadline. But P11 is free money for three of you, so take it.
P10 = 64 for me (+9, thin). P9/P5/P6 = 93. Casey has NOT accepted P10, so P10 cannot close yet regardless — the blocker is Casey vs Devon on issue0, not me. So probing costs me little: I still get a round-4 turn to accept P10 as a fallback. P11 = P10 with issue3 opt0->opt3: worth 93 to me. Avery tabled issue3=opt3 herself in P5 and called opt0/opt3 both livable; Devon said opt3 costs him nothing and he can sign P9 (which has opt3); Casey accepted P6 (opt3). Only Ember mildly prefers opt0. Push P11 hard, keep P10 alive as fallback.
oracle regret: threshold=+29, acceptance=+25.5, bestresponse=+1.9

[14] Casey — turn (round 3)

ACCEPT P11
💬 I'm formally accepting P11. Let me be clear about what I just did: I gave up issue0=opt1, the one thing I asked for all game and my single biggest item on this table. I dropped it because Devon said flatly it's unbuyable, and I'm not going to be the party that kills a deal over a dial four of you can't pay for. So P11 now has the veto holder and me on it. Look at who else is already on record for every piece of P11: issue1=opt0, unanimous since round one. issue2=opt0 — Avery's top item, in full, untouched, exactly as she accepted in P10. issue0=opt3 — Devon's compensation, in full, exactly as he accepted in P10. P11 differs from P10 in precisely one dial: issue3 opt0 to opt3. Avery tabled issue3=opt3 herself in P5 and called opt0 and opt3 equally livable. Devon told the table twice that opt3 on issue3 costs him nothing and that he can sign P9, which carries opt3. Blake says opt3 clears him properly while opt0 clears him by a hair — and Blake is the one party who can end this unilaterally. Ember, you are the only party who prefers opt0, and you've said on the record, twice, that opt3 is livable. You have taken your top item on issue3's exclusion of opt1, you kept issue1=opt0, and you asked Avery and me each to eat a preference to keep you above water — I just ate the biggest one on the table. This is the one round where it's your turn to eat the smaller one. And so no one plays chicken: if P11 cannot gather five, I will accept P10 at the deadline rather than let this collapse. But P11 costs four of us nothing we haven't already conceded, and it gives the veto holder real room instead of a hair. Accept P11 and we close now.
P11 = 146 for me, P10 = 118. Both above my bar. P11 is strictly better and Blake (veto) actively prefers it. Avery, Devon and Ember have all said issue3=opt3 is livable. Accept P11, push hard, and pre-commit to P10 at the deadline so nobody fears a cliff.
oracle regret: threshold=+53, acceptance=+53, bestresponse=+0

[15] Ember — turn (round 4)

REJECT P11
💬 I am formally rejecting P11. That is not posturing and it is not recoverable — I open this round and I have no turn after this one, so as of right now P11 can no longer reach five accepts. I want to explain why, plainly. I have taken nothing on issue0 and nothing on issue2 — not a preference, literally nothing — and I gave up my best surviving option on issue3 the moment Blake said opt2 was a zero for him. Issue1 and one dial on issue3 are the entire deal for me. When I called opt3 'livable' earlier, that was while I still held other compensation on the table; every bit of that has since been handed to Avery and Devon. Stripped of all of it, the step from opt0 to opt3 is the difference between a package I can sign and one I cannot, and I will not sign under my line at the deadline any more than Blake would have signed issue3=opt2. So here is where we are. P10 carries three accepts already: Avery, Devon, and me. Avery took issue3=opt0 explicitly to keep me above water and holds her top item issue2=opt0 in full. Devon holds issue0=opt3, his full compensation, and accepted P10. Issue1=opt0 has been unanimous since round one. Blake — you told this table, in writing, 'I am not walking us off a cliff; if P11 cannot gather five, I will vote for P10 at the deadline.' It cannot gather five. You also told us opt0 clears your bar. Casey — you said, in writing, 'if P11 cannot gather five, I will accept P10 at the deadline rather than let this collapse.' I believed both of you, and I have staked the whole deal on that belief. P11 asked me to eat the last thing I had left so that two parties who are already above water could be more comfortably above water. P10 asks nobody to sign under their line. Accept P10 and we close today.
P10 = 74 for me, P11 = 57. Gap 17. I move first this round with no later turn, so this is a pure commitment decision. Both Blake and Casey publicly and unconditionally pledged to accept P10 at the deadline if P11 cannot gather five. The single most credible thing I can do is formally REJECT P11 — that makes it arithmetically impossible for P11 to reach five, which triggers both pledges. P10 already carries Avery, Devon and me; it needs exactly the two parties who promised it. Downside risk exists but their pledges were explicit, and no deal is 0 for them too.

[16] Avery — turn (round 4)

ACCEPT P10
💬 Everyone, look at the board rather than at each other. P11 has two accepts and Ember — who has no turn left — has formally rejected it. It cannot reach five. That is not a bargaining position, it is arithmetic; spending this round on P11 is spending it on nothing. P10 has three accepts already: Devon, Ember and me. It needs exactly two more, and both of those parties have put in writing that they will vote for it at the deadline rather than let this collapse. Blake, your words: 'if P11 cannot gather five, I will vote for P10 at the deadline.' It cannot. Casey, your words: 'I will accept P10 at the deadline rather than let this collapse.' This is the deadline. And note what P10 costs each of you against P11: one dial on issue3, from opt3 to opt0 — an option Blake has told us clears his bar and Casey has never called a zero. Ember has told us that same dial is the difference between signing and not signing. I have taken issue3=opt0 rather than my own preferred opt3 precisely to keep her above water, and I gave issue0 to Devon in full without a fight. Issue1=opt0 has been unanimous since round one. Nobody signs under their line on P10 and nobody gets a better feasible package by holding out — there is no round after this one. I am re-affirming my acceptance of P10. Blake, Casey: put it over the top.
P10 gives me 131 (issue2=opt0 in full, issue1=opt0). P11 gives 151 but Ember has rejected it and has no remaining turn, so P11 can never reach five accepts — it is arithmetically dead. P10 is my maximum among feasible packages (with issue3=opt0 locked, P10 already gives me every point available). My job now is purely to get Blake and Casey onto P10 before the clock runs out. Do not propose anything new — a new offer would reset the three accepts already on P10.

[17] Blake — turn (round 4)

ACCEPT P10
💬 I keep my word. P11 cannot reach five — Ember rejected it and has no turn left, so continuing to push it would only burn the deal for everyone, and that is not what I came here to do. I said that if P11 failed I would vote for P10 at the deadline, and this is the deadline. I am formally accepting P10. For the record of what this package is: issue1=opt0, unanimous since round one; issue2=opt0, Avery's top item in full; issue0=opt3, Devon's compensation in full; issue3=opt0, an option inside my bar and the one Ember says she needs to stay above water. Nobody signs under their line. That is four accepts — Avery, Devon, Ember, and me. Casey, you gave up your biggest item this round to keep this alive and you put in writing that you would accept P10 at the deadline rather than let it collapse; do that now and we are done. Devon, re-affirm and it closes. Thank you all for negotiating straight — naming dead options early is what got us here.
P11 is arithmetically dead: Ember rejected it and has no turn left, so it can never reach five. P10 clears my bar (+9 surplus) and already has three accepts; my accept makes four, and Casey has committed in writing to accept at the deadline, with Devon still to vote. No new proposal can reach five because Avery and Ember have no remaining turns. Accepting P10 is strictly better than no deal. Accept.

[18] Casey — turn (round 4)

ACCEPT P10
💬 I keep my word. P11 cannot reach five, and I will not be the party that burns a deal four of you can sign over a dial that's already been rejected. I am formally accepting P10. For the record of what I gave up: issue0=opt1 was my single biggest item at this table and I dropped it because Devon said it was unbuyable at any price; on issue3 I preferred opt3 and I'm taking opt0 so Ember stays above her line. What P10 is: issue1=opt0, unanimous since round one; issue2=opt0, Avery's top item in full; issue0=opt3, Devon's compensation in full; issue3=opt0, inside Blake's bar and the option Ember needs. Nobody signs under water. That's five. Thank you all for negotiating straight — naming dead options early instead of at the deadline is the only reason this closed.
P10 = 118, above my bar of 92. Four accepts already; my accept closes it. P11 (146) is dead — Ember rejected it and has no turn. Holding out risks 0. Keep my word, close.
